Why Thin Film Instead of Kapton® for your Flexible Microcircuits?

Posted by Shawn Martin on 12/20/16 3:51 PM

The ultimate factor in deciding when not to use the Kapton polyimide film manufacturing method is a combination of desired size and flexibility. Basically, the moment you’re uttering “micron” as opposed to “mils”, best to start thinking about thin film.

Electroforming, electrochemical machining, and electrical discharge machining all use electrolytic baths. But only one is additive, which helps explain why it’s also more precise.

Electroforming Versus Photochemical Machining

Posted by Shawn Martin on 6/14/16 11:12 AM

Both methods employ photolithography to fabricate nano-scale structures. But where one adds material to exposed surfaces, the other subtracts — with far different results.

 

For a very long time component makers have widely applied photolithography as the go-to technique for fabricating extremely small features. The tiny circuits in a computer chip are the most obvious example. One reason is simplicity.
